RESUMO
UNLABELLED: The benign esophageal stenoses (BES) are common complications owing to many etiologies: gastroesophageal reflux, ingestion of corrosive agents, esophageal surgery, radiotherapy, postendoscopic variceal sclerotherapy, drug ingestion, prolonged nasogastric intubation, extrinsic compression and esophageal webs. Esophageal dilatations are worldwide recommended to treat this complication, employing dilators of many types and diameters and facilitating the food ingestion. PURPOSE: Evaluation of the results and advantages of the conservative treatment of the BES using esophageal dilatations, in outpatient service of upper digestive endoscopy. METHODS: During the period from 1981 to 1999, 500 patients with BES were treated and followed up at the Gastrocenter - UNICAMP, in an individually Program of Esophageal Dilatation for each case. The highest number of cases was under ages from 31 to 60 years old (52,8%), and males (59,2%). The most predominant etiologies were: peptic stenosis (30,4%), caustic ingestion (23,6%), anastomosis (23,2%), megaesophagus (8,0%) and prolonged nasogastric ingestion entubation (6,4%), totalizing 91,6% of the BES. Most of patients (94,2%) were submitted to the maximum of 25 dilations. Dilators from 10,5 to 16 mm were employed in 95,6% of the cases. The duration of the treatment was 24 months in 76,2% of the BES. Esophageal perforations occurred in 6 patients (1,2%), without mortality. RESULTS: Were considered excellent, good and bad results, respectively in 76,2%, 18,2% and 5,6% of the cases. On the other hand, excellent results were recorded in 81,0% of the peptic stenosis, 66,1% of the caustic stenosis and 82,7% of the anastomotic stenosis. The conservative treatment failed in 9,3% of the caustic stenosis, 4,3% of the anastomotic stenosis and 3,9% of the peptic stenosis. Thus, the caustic stenosis were unsuccessfull in the highest percentage of unsuccessful. CONCLUSION: The conservative treatment using guidewire dilators (Savary-Gilliard and Eder-Puestow) is the first choice in the BES, is effective for long time, with short complications and the surgical treatment is indicated only when the dilatations failed.

As estenoses benignas do esôfago (EBE) säo complicaçöes muito freqüentes, resultado de várias etiologias, a saber: refluxo gastro-esofágico, ingestäo de agentes corrosivos, pós-cirurgias do esôfago, pós-radioterapia no tórax, pós-escleroterapia endoscópica de varizes do esôfago, ingestäo de medicamentos, uso prolongado de cateter nasogástrico, compressäo extrínseca e membranas esofágicas congênitas. As dilataçöes esofágicas säo recomendadas no tratamento dessa complicaçäo, empregando dilatadores de vários tipos e diâmetros, facilitando ao doente a ingestäo alimentar. OBJETIVOS: Avaliaçäo dos resultados e vantagens do tratamento conservador das EBE através de dilataçöes esofágicas realizadas ambulatorialmente com auxílio da endoscopia digestiva flexível. MÉTODOS: No período de 1981 a 1999 foram tratados, conservadoramente e seguidos no Gastrocentro -- UNICAMP, 500 doentes com EBE, através de um Programa de Dilataçöes Esofágicas instituído para cada caso. A maioria era do sexo masculino (59,2 por cento) e a faixa etária mais acometida encontra-se entre 31 anos e 60 anos, compreendendo 52,8 por cento dos pacientes em estudo. As estenoses mais prevalentes foram as estenoses pépticas (30,4 por cento), cáusticas (23,6 por cento), de anastomoses (23,2 por cento), por megaesôfago (8,0 por cento) e por uso prolongado de cateter nasogástrico (6,4 por cento), perfazendo um total de 91,6 por cento das EBE. Quanto ao número de procedimentos, 94,2 por cento dos casos foram submetidos a no máximo 25 dilataçöes do esôfago. Em 95,6 por cento deles foram utilizados dilatadores com diâmetro entre 10,5 mm e 16,0 mm. A duraçäo do tratamento foi até 24 meses em 76,2 por cento dos casos. Perfuraçöes esofágicas ocorreram em seis doentes (1,2 por cento), sem mortalidade. RESULTADOS: Foram considerados bons em 76,2 por cento, regulares em 18,2 por cento e maus em 5,6 por cento dos doentes. O sucesso do tratamento variou conforme a etiologia da estenose, ocorrendo bons resultados em 81,0 por cento das estenoses pépticas, em 66,1 por cento das estenoses cáusticas e em 82,7 por cento das estenoses de anastomoses. A falha do tratamento conservador ocorreu em 9,3 por cento das estenoses cáusticas, 4,3 por cento das estenoses de anastomose e 3,9 por cento das estenoses pépticas. A estenose cáustica propiciou a falha maior da terapêutica conservadora em relaçäo aos demais. CONCLUSÄO: O tratamento conservador, através de dilataçöes orientadas por fio-guia...

BACKGROUND: Gastroesophageal reflux disease is highly common worldwide and surgical treatment is being indicated more frequently. Currently, laparoscopic is the access of choice and several antireflux techniques may be used. We prefer a modified Nissen technique. PURPOSE: To analyze preoperative clinical and functional parameters and compare with postoperative outcome of a modified valve technique performed by laparoscopy. METHODS: A group of 59 patients underwent laparoscopic modified Nissen valve. Preoperative diagnosis was made by radiological contrast exams and endoscopy in all patients. Esophagus manometry was performed in 35 patients and scintigraphy scan in 15 patients. Complicated esophagitis occurred in 54.2%, with 21 (35.6%) patients presenting a Barrett's epithelium. Laparoscopic surgery was performed in all patients with no conversion to open surgery, with an average time of 123.9 minutes. RESULTS: There were no intraoperative complications. Hospital discharge occurred in an average of 47.6 hours. Symptoms as dysphagia, pain, regurgitation and flatus occurred in 48.1% of the patients in the first thirty days. Average follow-up was 20.8 months. Postoperative radiological, endoscopic, manometric and scintigrafic scan exams showed a significant improvement, as well as clinical assessment using Visick's classification, which showed excellent and good results in 93.1% of the patients. CONCLUSION: Comparative analysis of clinical assessment and exam results lad us to conclude that modified Nissen surgery by laparoscopic access corrects gastroesophageal reflux in most patients followed-up.

A doença do refluxo gastroesofagiano é muito freqüente na populaçäo e o tratamento cirúrgico é indicado em um número respeitável de pacientes. A escolha da via de acesso é a laparoscopia. Várias técnicas anti-refluxo podem ser empregadas e preferimos a técnica de Nissen modificada. OBJETIVO: Analisar os parâmetros clínicos e funcionais pré-operatórios comparados com os mesmos parâmetros pós-operatórios com a técnica empregada. MÉTODOS: Um grupo de 59 pacientes foi submetido a tratamento cirúrgico pela técnica de Nissen modificada videolaparoscópica. O diagnóstico pré-operatório foi feito por exame radiográfico contrastado e endoscopia digestiva alta em todos os pacientes. A manometria do esôfago realizada em 35 e a cintilografia em 15. Esofagite complicada ocorreu em 54,2 por cento sendo 21 pacientes (35,6 por cento) com epitélio de Barrett. A técnica cirúrgica laparoscópica foi concluída em todos os pacientes. O tempo médio de cirurgia foi de 123,9 minutos. RESULTADOS: Näo ocorreram complicaçöes intra-operatórias. A alta se deu em média com 47,6 horas. Sintomas de disfagia, dor, epigastralgia, regurgitaçäo e flatulência até o 30° dia ocorreram em 48,1 por cento dos pacientes. Ocorreu uma reoperaçäo por recurrência da doença e um óbito por necrose do fundo gástrico. O seguimento médio foi de 20,8 meses. Os exames pós-operatórios radiográficos, endoscópicos, manométricos e de cintilografia mostraram melhora significativa, bem como a avaliaçäo clínica, que mostrou excelentes e bom resultados em 93,1 por cento dos pacientes. CONCLUSÄO: A cirurgia de Nissen modificada videolaparoscópica corrigiu a doença do refluxo gastroesofagiano na maioria dos doentes acompanhados, associada à baixa morbimortalidade

BACKGROUND: Endoscopic sclerotherapy is widely accepted as an effective treatment for the eradication of esophageal varices in patients with portal hypertension and a history of upper gastrointestinal bleeding. The objective of this study was to assess the effectiveness and safety of absolute ethanol as an alternative sclerosing agent to the commonly used 5% ethanolamine oleate. METHODS: One hundred fifty-seven patients with portal hypertension and a history of variceal bleeding were randomly assigned to sclerotherapy with absolute ethanol (n = 66) or 5% ethanolamine oleate (n = 91) between January 1992 and July 1994. Once eradication was achieved, these patients were prospectively followed until September 1998. RESULTS: Sclerotherapy with both sclerosants resulted in similar eradication rates (approximately 90%), with comparable numbers of sessions required for eradication (5.4 and 5.9 sessions for absolute ethanol and 5% ethanolamine oleate, respectively). Similar complication and recurrent bleeding rates were observed among both groups. CONCLUSION: Sclerotherapy with absolute ethanol is as effective as with 5% ethanolamine oleate in preventing further bleeding in patients with portal hypertension.

UNLABELLED: The laparoscopy has been more and more frequently indicated in the last years, for the complementary diagnosis of intraabdominal diseases and abdominal repercussion of systemic diseases. Modern equipaments including videolaparoscopy and the use of either forceps or biopsy needle permit higher safety and significant diagnostic capacity. PURPOSE: To perform laparoscopy for the diagnosis of intraabdominal and sistemic diseases. METHODS: During the last 9 years 168 patients were submitted to laparoscopy and the main indications were: ascites--43 cases (25.5%); liver diseases--42 cases (25%); gastric cancer--37 cases (22%); lymphoma--17 cases (10.1%); abdominal tumour--9 cases (5.4%); peritoneal tuberculosis--8 cases (4.8%); liver tumour--6 cases (3.6%); mesenteric cyst--1 case (0.6%) and other diseases--5 cases (3.0%). Ninety nine patients were male (58.9%) aging from 9 to 78 years old (median 47.6 years). Liver biopsies were performed in 92 cases (54.7%) and other tumour biopsies in 26 cases (15.4%). RESULTS: The diagnosis of the diseases were established or confirmed by laparoscopy in 145 patients (86.3%). In 25 cases of gastric cancer (67.5%) laparoscopy contraindicated the laparotomy, owing to advanced disease. Two patients presented bleeding (1.2%) after liver biopsies and laparotomy was immediately indicated. One of them, whose diagnosis was systemic lupus, presented abdominal abscess, bronchopneumony and died (0.6%). CONCLUSION: Laparoscopy has small number of complications, and when employed as a diagnostic complementary method therapeutic procedures, avoids laparotomies and accelerate therapeutic procedures.

BACKGROUND: Management of Barrett's esophagus requires reduction of gastric acid secretion and screening for the development of adenocarcinoma. However, the current therapeutic options are ineffective in reducing the Barrett's mucosa. The aim of this study was to evaluate the effectiveness of endoscopic thermal coagulation of Barrett's mucosa as an alternative therapeutic approach and the recurrence of the disease in the long term. METHODS: Fourteen patients (11 men, 3 women; mean age 45.7 years) with Barrett's esophagus participated in the study. They underwent laparoscopic fundoplication and were symptom free with no defective fundoplication wraps before therapeutic endoscopy. Endoscopic thermocoagulation was performed with a flexible videoendoscope and a bipolar probe. Mucosal areas were treated once a month until the Barrett's mucosa disappeared. Endoscopy was performed 1 and 7 months after completion of the treatments and once a year thereafter. RESULTS: The mean follow-up period was 21.6 months (range 18 to 30 months). The mean length of Barrett's esophagus was 4.8 cm. Successful ablation of the columnar epithelium was achieved in 3.7 sessions, as defined by demonstration of normal squamous epithelium at histologic examination of biopsy samples collected after completion of the treatments and at follow-up evaluations. Three patients experienced short-term (10 days) odynophagia or dysphagia. All patients were symptom free with no evidence of Barrett's esophagus at the end of the study. CONCLUSIONS: Bipolar electrocoagulation after antireflux operations is effective in promoting regression of Barrett's esophagus and has few complications. Endoscopic thermal coagulation might reduce risk for adenocarcinoma among these patients.

BACKGROUND AND OBJECTIVES: Transmediastinal gastric transposition and pharyngogastric anastomosis is perhaps one of the most widely accepted methods for restoration of the alimentary continuity after pharyngoesophageal resection. The need of neck dissection, mediastinal tracheostomy, and previous radiotherapy may favor exposure and rupture of major vessels. Protection with omentum may prevent this complication. A comprehensive review of omentum flap use in surgery was undertaken. METHODS: A modified omentum pedicled flap was used in 6 out of 36 patients submitted to total pharyngolaryngoesophagectomy and gastric transposition (PLE>). RESULTS: None of the patients had major vessel rupture as compared with a 13% carotid and innominate artery rupture of a series of 30 patients previously operated on without omentum pedicled flap protection. CONCLUSIONS: The omental pedicled flap, performed as described, may provide reliable protection for carotid and innominate artery exposure, adding little time to the procedure.

A laparoscopia tem sido mais freqüentemente indicada nos últimos anos na completaçao diagnóstica de afecçoes abdominais e na identificaçao de repercussoes abdominais de doenças sistêmicas. Modernos equipamentos incluindo video-laparoscopia e o uso de agulhas de biópsias e outros instrumentos permitem elevada segurança e significante capacidade diagnóstica. Objetivo. Empregar a laparoscopia no diagnóstico de doenças abdominais e sistêmicas. Métodos. Durante os últimos 9 anos, 168 doentes foram submetidos a laparoscopia e as principais indicaçoes foram: ascites (43 casos - 25,5 por cento); doenças hepáticas (42 casos - 25 por cento); câncer gástrico (37 casos - 22 por cento); linfomas (17 casos - 10,1 por cento); tumores abdominais (9 casos - 5,4 por cento); tuberculose peritoneal (8 casos - 4,8 por cento); tumores hepáticos (6 casos - 3,6 por cento); cisto mesentérico (1 caso - 0,6 por cento) e outras doenças (5 casos - 3,0 por cento). Noventa e nove pacientes eram masculinos (58,9 por cento), com idade variando de 9 a 78 anos (47,6 anos). Biópsias hepáticas foram realizadas em 92 casos (54,7 por cento) e outras biópsias tumorais em 26 casos (15,4 por cento). Resultados. O diagnóstico da doença foi estabelecido ou confirmado em 145 casos (86,3 por cento). Em 25 casos de câncer gástrico (67,5 por cento), a laparoscopia contra-indicou a laparotomia em funçao de detecçao de doença avançada. Dois pacientes apresentaram hemorragia (1,2 por cento) após biópsias hepáticas e a laparotomia foi imediatamente indicada. Um doente, cujo diagnóstico era de lupus sistêmico, apresentou abscesso abdominal, broncopneumonia e faleceu (0,6 por cento). Conclusao. O procedimento tem pequeno número de complicaçoes e quando empregado como método diagnóstico complementar, evita a laparotomia e agiliza medidas terapêuticas.

The authors report a case of a 13-year-old girl with Barrett's esophagus who underwent antireflux surgery and was subsequently treated with endoscopic thermal coagulation using bipolar electrocoagulation. Follow-up endoscopy 15 months after completion of the endoscopic therapy showed normal esophageal mucosa without intestinal metaplasia. Longer follow-up is needed to assess the long-term effects of endoscopic treatment of the Barrett's mucosa with thermal coagulation, and this procedure should still be considered under investigation.

It is very important in the clinical practice to identify the individuals with Barrett's esophagus, because they are at risk to develop adenocarcinoma in the columnar epithelium. The objective of this research is to verify the incidence of this specific kind of epithelium at the "Gastrocentro", at State University of Campinas-UNICAMP, Campinas, SP, Brazil, among the total of 15,976 upper digestive endoscopies, performed from january of 1992 to December of 1995. From the total examinations performed were identified 2,381 patients (14.9%) presenting reflux esophagitis (grades I-IV, Savary-Miller). Among this group of patients, the endoscopist suspected of Barrett's esophagus in 110 cases (4.6%) and biopsed the distal esophagus. However, only in 85 cases (77.3%) the pathologist confirmed the diagnosis of Barrett's epithelium. The patients with Barrett's esophagus were 53 males (62.3%), presenting the mean age of 52.2 years and the following grades of esophagitis: grade I-33 cases (38.8%); grade II-15 cases (17.7%); grade III-15 cases (17.7%), grade IV-12 cases (14.1%) and without esophagitis-10 cases (11.7%). The incidence of Barrett's esophagus among the patients with reflux esophagitis was 3.57%, and among the total of examinations performed at the "Gastrocentro" during the period of four years was 0.53%, totalizing 22,4 cases/100,000 habitants.

During the period from August 1st, 1990 to June 15, 1992, 117 patients with portal hypertension and upper gastrointestinal bleeding were examined at the "GASTROCENTRO"--State University of Campinas--UNICAMP, Campinas, SP, Brazil few hours after hospital admission. The objectives were to study the association of gastroduodenal acute lesions and esophageal varices. The predominant ages were thirties and sixties years (83.76%), being 70.08% of males. The hematemesis occurred in 94.02% of the cases. The etiologies of the bleeding were: esophageal varices, 47.87%; gastroduodenal acute mucosal lesions, 34.19%; gastric varices, 9.4%; gastric ulcers, 5.98% and duodenal ulcers, 2.56%. The authors concluded that exists a significant association of acute gastroduodenal lesions and esophageal varices causing upper gastrointestinal bleeding. It is essential to examine early and in detail the gastroduodenal mucosa during upper digestive endoscopy in the patient with portal hypertension and esophageal varices to diagnose the etiology of the bleeding. It is advisable to perform endoscopic examination twice a year when the dyspeptic symptoms are constant, with previous treatment for gastroduodenal acute mucosal lesions or peptic ulcers, and annual in the others.

PURPOSE: gastroduodenal mucosa of two groups of patients with chronic liver disease was studied: schistosomotic mansoni patients (SH) and non-schistosomic patients (NSH). Results were compared to serum-gastrin levels. TYPE: prospective study. PLACE: Unicamp University Hospital (Hospital das Clínicas), Campinas, São Paulo, Brazil. PATIENTS: 24 patients were included in the results, out of 26 patients studied. Two groups of study: 12 patients with schistosomiasis and liver fibrosis (SH), and 12 patients with liver cirrhosis (NSH) secondary to alcoholism or to hepatitis. PROCEDURES: esophagogastroduodenoscopies and biopsies of gastric antrum and duodenum. Function tests of the liver were also studied. RESULTS: results of gastrinemia were found within normal ranges in both groups. Student test ("t") did not show differences between groups at the 5% level. However, patients with chronic liver cirrhosis had more significant and severe endoscopic findings and chronic inflammatory processes of the gastroduodenal mucosa (acute gastritis, duodenitis and ulcers) than patients with liver fibrosis. CONCLUSIONS: patients with liver cirrhosis due to high risk of gastroduodenal bleeding should be maintained under continuous vigilance, appropriate diet and mucosa cytoprotectors. Furthermore, more research is required to study the etiology of gastroduodenal lesions in these specific groups of patients.

Benign neoplasms are rare events in the extrahepatic biliary ducts, and scanty literary references on the subject are available. Four cases of obstructive jaundice caused by benign tumours of the extrahepatic biliary ducts have been reviewed. Two of them have also displayed lithiasis of the gallbladder and common bile duct. In three cases histopathologic confirmation was obtained, in contrast to the remaining case in which only a gross pathologic presumptive diagnosis was possible. Three patients underwent surgical resection, and in one of them hepatojejunostomy was performed. The patient with a presumptive diagnosis of "inflammatory polyp" was not submitted to surgery, due to the special circumstances of the case. The undisturbed follow-up of the four cases attested to the worthiness of the surgical procedures.
